I agree with you, myjoy. I used to see a chiropractor...a very good one...and this is what happened to me.
I walked in to my chiropractor's office and almost couldn't walk out. He adjusted me and left the room. I was in horrible pain and almost couldn't get my slacks back on because I couldn't lift my legs! I shuffled out and the pain felt like someone was driving a stake up throught my spinal column and I thought I was going to pass out. It caused me to break out in a sweat.
When I got home, I laid down in bed with ice on my back. It was right around Christmas and I tried opening cards to get my mind off the pain but the tears were streaming down my cheeks. When I tried to get back out of bed to use the bathroom, I couldn't! The "electrical shocks" that ran up my spine wouldn't allow me to get in a sitting position. I asked my husband to get me a pan...just in case I had to use it.
I decided I had to give it one more try to sit up. If I couldn't make it, I was going to have my husband call the emergency squad. I made it...barely...and slept sitting up for 1 1/2 years until my back felt good enought to lie back down again. Boy! did I learn a lesson.
I really question this procedure. Many of us have arthritis in our spines, disc problems, etc. Also, if it is this compression of the spine that is causing fibro, why do we have so many young people on the forum with fibro?
Lastly, I Googled this and the only place you hear about this procedure is on this doctor's web site. That puts a red flag up for me.
